Performance analysis of DD-DPMZM based RoF link for emerging wireless networks
This paper demonstrates the analytical approach of Linearized Radio over Fiber (RoF) link based on Dual-Drive Dual Parallel Mach Zehnder Modulator (DD-DPMZM) by properly adjusting the phase shifters and biasing of the Mach Zehnder Modulator (MZM). Two input RF Source at 7 and 8 GHz applied in the used RoF link. The proposed RoF link consists of Mach Zehnder Modulator (MZM), Parallel combination of Mach Zehnder Modulators, optical fiber, and photodetector (PD). Third Order Intermodulation Distortions (IMD3) factor act as a major issue, which is responsible as performance degradation factor. Major sources of IMD3 spurious components have been investigated and suppressed in theoretical analysis before photodetection. The proposed method is designed with the help of OptSim simulation software, to confirm and validate the analytical analysis and simulation results. Analytical analysis & simulation results show that, 40 dB suppression found in IMD3 spurious components, and 30 dB.Hz2/3 enhancement found in Spurious Free Dynamic Range (SFDR), for the proposed linearized RoF link as compared to conventional MZM RoF link. The Measured SFDR is also founded as 26 dB.Hz2/3, 5 dB.Hz2/3, & 10 dB.Hz2/3 for different optical fiber impairments as 8 km, 10 km & 15 km respectively for used DD-DPMZM based RoF link.
